COLLABORATIVE RESEARCH: Interpluton Wall Rock Screens in the Sierra Nevada and their Bearing on Pluton Emplacement Processes

9814788科尔曼在复合岩基中分离单个侵入体的变质岩离散屏的保存是一个长期存在的和内在有趣的问题，涉及到空间如何为侵入岩浆提供。 相当大的努力已经针对屋顶挂件，但围岩屏幕可能提供相当多的见解侵入过程，以及，但很少研究。 来自犹他州大学、北卡罗来纳州大学和波士顿大学的研究人员之间的这一合作项目将研究加州的Sierra内华达州的深成岩幕的例子，这些特征在那里得到了很好的发展和展示。 研究结果应该有助于理解变质幕是如何形成的，以及它们可能为理解岩体如何侵入地壳提供什么样的见解。

9814788Coleman The preservation of discrete screens of metamorphic rocks separating individual intrusions in composite batholithes is a long standing and inherently interesting problem that relates to how space is mad available to intruding magma. Considerable effort has been directed at roof pendants however wall rock screens may offer considerable insights into intrusive processes as well, but have been little studied. This collaborative project between investigators from the University of Utah, University of North Carolina and Boston University will study examples of pluton screens in the Sierra Nevada of California, where these features are well-developed and displayed. Results should help understand how metamorphic screens form and what insights they might offer in understanding how plutons intrude the earth's crust.
